Automotive upholstery punching die with punch convenient to replace

Abstract

The invention provides an automotive upholstery punching die with a punch convenient to replace. The automotive upholstery punching die with the punch convenient to replace is characterized by comprising a frame, an operation table, a base column and a punching device; by arranging the punching device, a locking ring is pulled downwards, a connecting column is inserted into a locking cylinder, and a connecting groove and a matching column are used in cooperation under the action of magnetic force of an upper magnet and a lower magnet; primary positioning of the connecting column and the locking cylinder is further achieved, the locking ring is loosened, so that the locking ring rebounds to the bottom of the locking cylinder under the strong elastic deformation recovery capacity of a spring, and the locking ring and the locking cylinder are locked under the action of the elastic force of the spring while racks are engaged with tooth grooves; and secondary positioning of a transition column and the locking cylinder is further achieved, and locking positioning of a stamping part is achieved. According to the automotive upholstery punching die with the punch convenient to replace, the installation process is simpler and more convenient, time and labor are saved, the replacement time of the stamping part is shortened, and the replacement progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of punching dies, in particular to a punching die for automotive interior parts which is easy to replace punches. Background technique [0002] The punching process is a metal processing method, which is based on the plastic deformation of the metal, using the mold and punching equipment to exert pressure on the sheet, so that the sheet is plastically deformed or separated, so as to obtain a certain shape, size and High-performance parts; punching forming process plays an important role in the automobile body manufacturing process, especially the large-scale covering parts of the automobile body, because most of them have complex shapes, large structural dimensions, and some are space curved surfaces, and the surface quality requirements are high, so The use of punching processing methods to make these parts is unmatched by other processing methods; the cab of the truck, the front sheet metal parts, the carg...

AI Technical Summary

Problems solved by technology

[0005] For the above patent, there are still the following defects: in the above patent, although the replacement of the punch can be realized by setting the fixing device and the thread structure, when the punch to be replaced needs to be installed, the punch is first screwed to the base column through the thread structure Above, the base column and the punch are effectively limited by the fixing device, and the installation and fixation of the punch is realized. However, in the process of replacement, the thread needs to be screwed repeatedly. This operation process is not only cumbersome, time-consuming and labor-intensive, but also prolongs the The long replacement time of the punch slows down the replacement progress, making it inconvenient to replace, the replacement efficiency is low, and the thread is prone to wear and tear, which makes the installation of the base column and the punch unstable, which makes the punch shake during the stamping process. The stability of the punch installation is reduced, which in turn affects the punching quality of the interior parts and increases the probability of defective products
